T 0 aZZ whom it may concern:

Be it known that I, GRo-vnn C. STACEY, a citizen of the United States, residing at Dallas, in the county. of Dallas and Stateof Texas, have invented certain new and useful Improvements in Sand Extractors, ofwhich the following is a specification. 7

Hy invention relates to sand extracting devices and more particularly to devices for cleaning sand-or dirt from the suction draft in cotton cleaning and elevating devices; and the object is to provide a simple and useful extracting device for use of cotton ginners, which is interposed in the suction line of a cotton cleaning and elevating apparatus wherein the cotton is elevated a suction fan. Throughout the cotton regions of the United States and more particularly in the sandy sections of the country in the States where cotton is raised, the ginners have experienced a great loss by reason of the sand passing through the suction line into the fan, and the fan, running at a high rate of speed, throws the sand against the scroll sheet of the fan, cutting out the blast wheel and suction sheets. In some instances they have been known to cut them out in three days, necessitating the spending of a great deal of money to replace the blast wheel and scroll sheets of the fan. The apparatus hereinbelow described is interposed in front of the fan and extracts the sand from the air before the air, passes through the fan. The object of this invention is to provide a simple device by which the sand can be separated from the suction draft at small cost and the sand may be separated from the draft without any additional suction lines. Other objects and advantages will be fully explained in the following description, and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Fig. l is a side elevation of the sand cleaner. Fig. 2 is a plan view of the lower part of the device, being a horizontal section, taken on the line 22 of Fig. 1. Fig. 3 is a broken vertical section, taken on the line 3-3 of Fig. 2.

Similar characters of reference are used to indicate the same parts throughout the several views.

The improvements herein shown are located in the suction pipe 1 which leads from a cleaner 2 to asuction fan (not shown). The pipe 1 is intercepted'for, the purpose: of interposing the sand cleaning devices. The p pe 1. is intercepted at 3 and at 4:. A larger pipe .5 surrounds the end 6 of the main pipe for the purpose of forming sand or vacuum pockets for collecting'the same. A coneshaped deflector 7 is positioned above the open 3 end of the pipe section 6 and held there by sup-portsS which are attached to the pipe6 and to the interior of the deflector. There may be any suitable number of these supports. A11 annular space about thepipe 6 within the pipe 5 is divided into two pockets by spiral partitions 9 and 10 which commence at the upper end of the pipe 8 (and each runs around 180 degrees) and terminate in pocket valves 11. The sand will strike the deflector 7 and be thrown into the vacuum pockets about the pipe 6. All the sand will fall or slide down to the valves 11. The air will be drawn under the deflector 7 into the upper end of the pipe 6 and go on out through the fan (not shown). The valves 11 are of clothof the. usual type and sand will accumulate until it becomes heavy enough to dump. The sand will be dumped by gravity, opening the valves 11. The valves will then close automatically, being aided by, the suction through the pipe 6 and the suction fan.

Various changes in the construction, proportions and arrangement of the several parts may be made without departing from my 1nvention.

What I claim, is

1. A device for extracting sand from a suction line comprising a suction pipe in sections spaced apart, a larger pipe surrounding and forming a sand pocket with one section and tapering to and connected to theother section, and a deflector positioned within said tapering section for throwing the sand into said pocket.

2. A device for extracting sand, a suction l ne comprising a vertically disposed suctron pipe in sections spaced apart, a larger pipe surrounding the lower section and to and connected to the upper section, and

a deflector positioned within said tapering section for throwing sand into said pocket.

3. A device for extracting sand from a suction line, comprising a vertically disposed suction pipe in sections spaced apart, a larger pipe having a closed bottom and valves therein and surrounding the lower section and forming a sand pocket therewith and tapering to and connected to the upper section, spiral partitions dividing said pocket and forming means for directing the sand into said valves, and a deflector positioned in said tapering portion for deflecting the sand into said pocket.

4. A device for cleaningsand from a suction line comprising a vertically disposed suction pipe operatively connected with the cotton cleaner and being in sections spaced apart, a larger pipe surrounding a portion of the lower sectlon of saidsuction pipe and forming a vacuum pocket andtapering to and connected tothe upper section of said suction pipe, a bottom for said larger pipe and discharge valve in said bottom, spiral 5. A device for extracting sand from the suction line of cotton cleaning and elevating apparatus comprising a suction pipe in sections spaced apart and operatively connected to a cotton cleaner and the suction fan, a larger pipe surrounding the fan section of said pipe and forming a sand pocket therewith and tapering to and connected to the other section of said pipe, and means mounted between the said sections and within said tapering pipesection for deflecting sand into said pocket.

6. A device for extracting sand from the suction line of a cotton cleaning and elevating apparatus comprising a suction pipe operatively connected to a cotton cleaner and to a suction fan and being in sections spaced apart, a larger pipe surrounding a portion of the fan section of said pipe and forming a sand pocket therewith and tapering to and connected to the other portion of said pipe, dumping valves for said pocket, and means positioned between the sections of said suction pipe for deflecting sand into said pocket.
